Abstract :
This paper presents a robust MDPSK modulation classifier based on cumulants to frequency offset. The feature proposed in the algorithm is invariant with respect to constellation scale, rotation, the shift and the carrier frequency offset between transmitter and receiver. The invariant property is proved in theory. Through computer simulation the performance is evaluated and the results show that the improved classification algorithm is high in performance and valuable in practice.
